ios - How to disable CALayer implicit animations? -

it's driving me crazy! working on drawing application. let's working on uiview called sheet.

i adding sublayers view ([sheet.layer addsublayer:...]) , want draw them. creating cgimageref , putting layer's contents. it's animated , don't want that.

i tried everything:

• removeanimationforkey:
• removeallanimations
• set actions dictionary
• using actionlayer delegate
• [catransaction setdisableanimations:yes]

it's seems correct. don't understand why layer still animated ;_;
doing wrong? there secret way?

you have explicitly disable animations wrapping code in catransaction

[catransaction begin]; [catransaction setvalue:(id)kcfbooleantrue                  forkey:kcatransactiondisableactions]; layer.content = someimageref; [catransaction commit];
